Yes, Custom fenders will not have the holes for the Galaxie trim. NOS don't have the holes either. Engine badge holes needs to be drilled also as needed.
Yes they should fit. Differences --- 63 1/2 has lower roofline. Different glass and the seat brackets are shorter to make up for the headroom loss.Can someone tell me if the front fenders will interchange will all '63 and '63.5 models?
